TSP Process in Client Role

When the TSP process is in the client role as shown in Figure 2-2, if you assign local IP

address IPAddress1 to #lan1a, all outgoing connection requests are routed via

Subnet1; if you assign the remote IP address IPAddress3 to #lan1a, the incoming

connect requests on the server side of the connection are routed through Subnet3.

If you do not provide a local IP address when adding an SU, when the SU initiates a

connection request (client role), it allows TCP/IP the flexibility of choosing the local

subnet on its (TCP/IP’s) usual routing algorithm.

Figure 2-2 shows a TSP process (TSP1) and its associated subdevices (#lan1a, #lan1b,

and #lan1c). NSPDEVICE is required and must specify TCP/IP1. REMOTENSAP is

required and specifies the remote IP address on the server side of the connection.

LOCALNSAP is optional. If you don’t specify it, TCP/IP uses its routing table to

determine which local IP address or subnet to use and will use whatever subnet is

available.

Examples 1 and 2 associate the SUs with the local TCP/IP process and the remote IP

addresses.

Example 1:

#lan1a with TCP/IP1 and with IPAddress3

#lan1b with TCP/IP1 and with IPAddress3

#lan1c with TCP/IP1 and with IPAddress3

Example 2:

#lan1a with TCP/IP1 and with IPAddress3

#lan1b with TCP/IP1 and with IPAddress3

#lan1c with TCP/IP1 and with IPAddress4

TSP Process in Server Role

Figure 2-2 shows a TSP process (TSP2) and its associated subdevices (#lan2a, #lan2b,

and #lan2c). NSPDEVICE is required and must specify TCP/IP2. REMOTENSAP is

ignored. LOCALNSAP is required and specifies the local IP address on the server side

of the connection.

Examples 1 and 2 associate the SUs with the local TCP/IP process and the local IP

addresses.

Example 1:

#lan2a with TCP/IP2 and with IPAddress3

#lan2b with TCP/IP2 and with IPAddress3

#lan2c with TCP/IP2 and with IPAddress3

Example 2:

#lan2a with TCP/IP2 and with IPAddress3

#lan2b with TCP/IP2 and with IPAddress3

#lan2c with TCP/IP2 and with IPAddress4
